  		Fig 1. MR imaging performed 6 days after vision loss in the right eye. A, DWI shows subtle high signal intensity in the posterior right optic nerve (arrow). B, ADC map shows hypointense posterior right optic nerve (arrow).

  		Fig 2. MR imaging performed 15 days after vision loss in the right eye. A, DWI demonstrates marked diffusion restriction in the posterior right optic nerve (arrow). Note that there is no obvious signal-intensity change of the retrobulbar portion of right optic nerve (arrowhead). B, ADC map shows a hypointense posterior right optic nerve (arrow).
